SUMMARY
This article demonstrates how to create and manipulate a Word document using Automation from Delphi.
MORE INFORMATION
This article parallels two articles that describe the same process using Visual C++ and Visual Basic. For more information, please see the following articles in the Microsoft Knowledge Base:
220607 How To Automate Word to Perform Mail Merge From Visual Basic

220911 How To Automate Word to Perform a Mail Merge from Visual C++ and MFC

Building the Automation Sample

  1. Start Delphi. A new project should be created by default.
  2. Add a button to Form1.
  3. Replace the contents of the code window for Unit1 with the following:
    unit Unit1;interfaceuses  Windows, Messages, SysUtils, Classes, Graphics, Controls, Forms, Dialogs,  StdCtrls;type  TForm1 = class(TForm)    Button1: TButton;    procedure Button1Click(Sender: TObject);    procedure InsertLines(LineNum : Integer);    procedure CreateMailMergeDataFile;    procedure FillRow(Doc : Variant; Row : Integer;                 Text1,Text2,Text3,Text4 : String);  private    { Private declarations }  public    wrdApp, wrdDoc: Variant;    { Public declarations }  end;var  Form1: TForm1;implementationuses ComObj;Const wdAlignParagraphLeft = 0;Const wdAlignParagraphCenter = 1;Const wdAlignParagraphRight = 2;Const wdAlignParagraphJustify = 3;Const wdAdjustNone = 0;Const wdGray25 = 16;Const wdGoToLine = 3;Const wdGoToLast = -1;Const wdSendToNewDocument = 0;{$R *.DFM}procedure TForm1.InsertLines(LineNum : Integer);var  iCount : Integer;begin  for iCount := 1 to LineNum do     wrdApp.Selection.TypeParagraph;end;procedure TForm1.FillRow(Doc : Variant; Row : Integer;                 Text1,Text2,Text3,Text4 : String);begin  Doc.Tables.Item(1).Cell(Row,1).Range.InsertAfter(Text1);  Doc.Tables.Item(1).Cell(Row,2).Range.InsertAfter(Text2);  Doc.Tables.Item(1).Cell(Row,3).Range.InsertAfter(Text3);  Doc.Tables.Item(1).Cell(Row,4).Range.InsertAfter(Text4);end;procedure TForm1.CreateMailMergeDataFile;var  wrdDataDoc : Variant;  iCount : Integer;begin  // Create a data source at C:\DataDoc.doc containing the field data  wrdDoc.MailMerge.CreateDataSource('C:\DataDoc.doc',,,'FirstName, LastName,' +       ' Address, CityStateZip');  // Open the file to insert data  wrdDataDoc := wrdApp.Documents.Open('C:\DataDoc.doc');  for iCount := 1 to 2 do    wrdDataDoc.Tables.Item(1).Rows.Add;  // Fill in the data  FillRow(wrdDataDoc, 2, 'Steve', 'DeBroux',        '4567 Main Street', 'Buffalo, NY  98052');  FillRow(wrdDataDoc, 3, 'Jan', 'Miksovsky',        '1234 5th Street', 'Charlotte, NC  98765');  FillRow(wrdDataDoc, 4, 'Brian', 'Valentine',        '12348 78th Street  Apt. 214', 'Lubbock, TX  25874');  // Save and close the file  wrdDataDoc.Save;  wrdDataDoc.Close(False);end;procedure TForm1.Button1Click(Sender: TObject);var  StrToAdd : String;  wrdSelection, wrdMailMerge, wrdMergeFields : Variant;begin  // Create an instance of Word and make it visible  wrdApp := CreateOleObject('Word.Application');  wrdApp.Visible := True;  // Create a new document  wrdDoc := wrdApp.Documents.Add();  wrdDoc.Select;  wrdSelection := wrdApp.Selection;  wrdMailMerge := wrdDoc.MailMerge;  // Create MailMerge data file  CreateMailMergeDataFile;  // Create a string and insert it into the document  StrToAdd := 'State University' + Chr(13) +              'Electrical Engineering Department';  wrdSelection.ParagraphFormat.Alignment := wdAlignParagraphCenter;  wrdSelection.TypeText(StrToAdd);  InsertLines(4);  // Insert Merge Data  wrdSelection.ParagraphFormat.Alignment := wdAlignParagraphLeft;  wrdMergeFields := wrdMailMerge.Fields;  wrdMergeFields.Add(wrdSelection.Range,'FirstName');  wrdSelection.TypeText(' ');  wrdMergeFields.Add(wrdSelection.Range,'LastName');  wrdSelection.TypeParagraph;  wrdMergeFields.Add(wrdSelection.Range,'Address');  wrdSelection.TypeParagraph;  wrdMergeFields.Add(wrdSelection.Range,'CityStateZip');  InsertLines(2);  // Right justify the line and insert a date field with  // the current date  wrdSelection.ParagraphFormat.Alignment := wdAlignParagraphRight;  wrdSelection.InsertDateTime('dddd, MMMM dd, yyyy',False);  InsertLines(2);  // Justify the rest of the document  wrdSelection.ParagraphFormat.Alignment := wdAlignParagraphJustify;  wrdSelection.TypeText('Dear ');  wrdMergeFields.Add(wrdSelection.Range,'FirstName');  wrdSelection.TypeText(',');  InsertLines(2);  // Create a string and insert it into the document  StrToAdd := 'Thank you for your recent request for next ' +      'semester''s class schedule for the Electrical ' +      'Engineering Department.

  4. Press the F9 key to run the project. Click the button and Microsoft Word should start and display a sample letter.
